AUGUST SOHUBERT, OF ONEIDA, NEYV YORK.

SPRlNG-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 378.180, dated February21, 1888.

Application filed September 7 1887. Serial No. 249,007. (No model.)

To all whom it may concern.-

Be it known that I, Anousr Sennsnnr, of Oneida, in the county ofMadison, in the State of blow York, have invented new and usefulImprovements in Spring-Vehicles, of which the following, taken inconnection with the ac companying drawings, is a full, clear, and exactdescription.

This invention relates to the class of springgears usually designatedduplex spring, in which two springs are arranged respectively atopposite sides of and parallel with the axle.

The invention consists in supporting the springs on the axle by meansofspringarlns secured to the end portions ofthe axle and stand inglengthwise thereof and couplings connecting the ends of the springs tothe vibratory ends of the springarms. Said combination and arrangementof parts constitute a duplex spring-gen r which is compact, simple, andcomparatively inexpensive, and affords increased elasticity withoutinducing lateral swaying of the body of the vehicle.

The invention is fully illustrated in the annexed drawings, in whichFigure 1 is a front elevation of a springgear embodying my improvements.Fig. 2 is a top plan view of the same. Fig. 3 is a transverse section online :10 :1:,Fig. 2. Fig. 4 is a vertical longitudinal section on line y9 Fig. 2. Fig. 5 is a detached top plan view ol'onc ot' the spring-arms.Fig. (l is a side elevation of a modification of the spring-arm, andFig. 7 is an end view showing a modification of the spring'coupling.

Similar letters of reference indicate correspending parts.

A represents the axle, which is preferably formed with thedownwardlydeliected portion A A. On the end portions of this axle Imount spring-arms C (l, which stand in the direction of the length ofthe axle and are preferably secured to the top of thedownwardlydellected portions A A of the axle by clips c e,cn1bracing thesaid axle portions and superincumbent attaching ends of the spring-arms()0, as illustrated in Fig. 1 of the drawings, the free or vibratoryends of the spring-arms rising outward from the aforesaid portions ofthe axle. in order to prevent the spring-arm C from slippinglongitudinally on the axle, I provide the top of the latter with arecess, b, into which projects either the bolt or head of the bolt whichfastens together the leaves of which the spring-arm is composed, asillustrated in Fig. 4 of the drawings.

The free end of the spring-arm G is formed with a lateral flare, c, andwith an eye or sleeve, a, across the flare, and on opposite ends of saideye are hung the springs D D, which are arranged at opposite sides ofthe axle and terminate with the usual eyes for the reception of the boltby which they are coupled to the two spring-arms O O. The connection ofthe springs D D with the spring-arm G, I prefer to make by placing theeyes of thesprings D D in range with the eye a of the spring-arm andclose to the ends thereof and extending the couplingbolt through thethree eyes, as represented in Fig. 3 of the drawings, and on heavyvehicles I re enforce the said coupling by mounting on top of the eye aa saddle, It, which projects over the eyes of the springs D D andterminates with perforated earsrl tat the outersides of the springeyesand receives through said ears the ends of the bolt which couples thesprings D D to the spring-arm, as illustrated in Fig. 7 of the drawings.Ido not, however, limit myself to any specific coupling devices, as thesame admits of many modifications.

It will be observed that when the spring arms G G are arranged on thedownwardly-deflected portions AA of the axle, as shown in Fig.1oi'thedrawings,thespring-anns,when depressed, are brought to bear onthe axle nearer the oscillatory ends of the springarms, and thus thesupports of said arms are re-en forced in accordance with the increaseof the strain applied to them.

Although I prefer the arrangement of the springarnis G G, as beforedescribed, yet I do not wish to be limited in this respect, inasmuch asit admits of many modificationsmne ofwhich is illustrated in Fig. 6ofthe drawings,in which the spring-arm C is placed reverse from theposition hereinbefore described, and is rigidly mounted on thehorizontal end portion of the axle. The springs D D may be connected tothis spring-arm in the same manner as shown in Fig. 3 of the drawings.

Having described myinvention,what I claim as new, and desire to secureby Letters Patent, is-

1. The combination of the axle A, formed with the downwardly-curvedportions A A,
